Solution
The correct option is B amide Acid anhydrides on reaction with primary amines gives amide. It is an example of nucleophilic substitution reaction in which H atom of amino group is replaced with acyl group (R−C|| O −). The reaction is called acylation of amides. CH3−CH2−NH2+(CH3−C|| O −)2Opyridine−−−−−→ΔCH3−CH2−NH−C|| O −CH3+CH3−C|| O −OH
